So I listed my hardware setups running OpenBSD in this thread back in 2010 when I was starting out. Since then, I have moved away from the older single-core Athlon XP CPUs (except my trusty XP 2900) and replaced my dev setup with Core2Quad Q8200 & Core2Duo E8400 machines.

With these I am running pf along with DHCP & BIND and wireless on a separate subnet. I have added Squid & SquidGuard to the mix and I am currently evaluating NoSQL dBs to add.

This thing is really fast when it comes to disk I/O. The other Core2 boxes have 3GB SATA and only 1 has AHCI. When I do a squidGuard dB rebuild - systat reports about 30M/s on mechanical HDD (takes 20+ min) and 60MB/s on SSD (takes 8-10min). The E8400 will do 115MB/s sustaned during the rebuild (takes about 2min). When I get to the Cel 847 mentioned above with 6GB SATA and AHCI - I get 180MB/s sustained during the dB rebuild (takes 1m 10sec). Quite impressive indeed.

over powered firewall acting as 'AIO-server'
em0 connected to vhdsl2 modem with 100/10 connection,
em1 1gb switch for local net, and run0 as a backup connection into 4g lte modem.
I plugged in re0 for testing only, and forgot it there.

I moved my home, recently, and took the opportunity to install a new pair of low power, solid-state OpenBSD firewalls when I made the transition. The outer LAN's availability is managed by ifstated(8), the inner LAN uses carp(4). The firewalls keep pf(4) and dhcpd(8) in sync via Ethernet crossover.

Left to right on the shelf: a switch for the outer LAN, a cable modem, a pair of PC Engines Alix2d13 systems running OpenBSD, a switch for the inner LAN, and a wireless AP. This photo is being served to you from one of the Alix machines..

I recently acquired an HP-Proliant ML370-G4 with a PCI-X Smart Array 6404 SCSI U320 controller card that has a 192MB cache. It currently has two 146GB U320 10kRPM drives configured as a RAID0 array. I plan to add four more 146GB drives configured as a RAID5 array (it has a six disk drive cage).

The machine is built like a tank - redundant power supplies, ECC RAM throughout, hot-swap drives, six hot-swap fans, SDLT320 tape drive, etc. The quality of the hardware and thoughtfulness of the design are very impressive, especially considering that I snagged this sweet box for $200. OpenBSD is a perfect fit.

I have a few new additions (BeagleBone Black, new Dell laptop, etc...), but the Ultra5 and gang are all still chugging along like they always have. If I'm not mistaken, I've run the same firewall hardware since 2008, which has survived hard drive failures, fan failures, two moves (one cross country), and the like.

The only real change (aside from adding a few OpenBSD machines) is that I have more machines running STABLE than CURRENT now. Go figure.
